What Is Energy Isolation (Lock-Out Tag-Out)?

The modern age requires machines to build infrastructure and bring about development. The machines work regularly to produce items which could be anything from glue stick and television sets to tanks and missiles. One very important issue that arrives with these machines apart from industrial waste is ‘Safety’.

The safety is of the people who come in contact with the machines like workers, engineers, supervisors and so on. Energy Isolation helps protect these people from hazards caused by heavy machines & equipment.

Energy Isolation – It means separating all forms of energy from the machines and declaring the machine ‘safe’ for maintenance & service to go on. The hazards could be caused by mechanical, thermal or hydraulic forms of energy.

The Lock out Tag out procedure developed by OSHA (Occupational Safety & Health Administration) is worth mentioning here.

What is Lock Out /Tag out (LOTO)

LOTO is a safety procedure followed to declare the industrial machines safe. The machines shall be incapable of starting again without the prior knowledge of all the people involved.

Lock Out – It means locking the concerned device and keeping it away from any power-inducing source. The machine หวยออนไลน์ should not be capable of restarting again without warning.

This involves locking devices like:

• Circuit breakers
• Cable lockouts
• Valves & springs
• Disconnect switches
• Key combinations
• Pneumatic lockouts

Tag Out – This refers to a process of labeling the device as powerless. The attached pointer includes: why the tag is there, time of application of the tag, & name of the authorized person.

All LOTO devices must have some standard functions and should meet the following requirements.

• Identifying the authorized person
• High durability level
• A “Do not open, start” warning
• Uniform in color, size, print, shape and format
• Devices should resist early removal, except using specific tools like bolt cutters, wire cutters etc.
• Non-releasable tags

Basic steps of the procedure:

– Preparation for shutdown
– Notifying all employees
– Equipment shutdown
– Isolation from hazardous energy
– Dispelling of left-over energy
– Locking & Tagging the machines
– Performing maintenance or service activity
– Verification (observation, visual inspection & equipment testing)
– Removing Locks & Tags
– Notifying all employees to resume work
